天使一号广场(Co-operative集团新总部)容纳了32.8万平方英尺(约30472.2平方米)的高质量办公空间,经过专门设计,具有最大的灵活度。建筑结构及其机电系统的设置让使用者很容易就能重新布置其办公场所以及对空间进行细分,因而无论需求如何变化,建筑的功能永远都能合乎需要,而且不会耗费过多的改造资金。该项目获得了BREEAM标准“杰出”等级的全英国最高分,并且在商业领域的可持续设计中竖立了全新的国家级标准。

与Co-operative集团先前在曼彻斯特使用的综合体总部相比,天使一号广场能节省能耗50%,减少碳排放80%。由此可节省营业成本高达30%。

在项目中还运用了许多具有开创性的工程技术,其中包括双层立面,可最大化减少全年的供暖与制冷需求;地下混凝土接地导管,可为新鲜空气提供大量免费的暖气与冷气。混凝土的热质量在建筑物内部再次得到了使用,从办公室地面到天花板都采用了裸露混凝土,裸露面积达30万平方英尺(约27870.9平方米)。混凝土如同不断吸热的海绵,被动地吸收热量,减少了为建筑物制冷所需的能量。废气最终借助中庭的自然烟囱效应从阳台排出,因而不再需要在核心筒安装挤占空间的大型排气装置。这些废气在离开建筑之前还会经过一台热交换器,回收热量用于为办公室的新鲜空气加热。

3Dreid建筑师事务所合并了废水回收和雨水收集系统,以确保降低耗水量。Co-operative实行本地采购和可持续性原则,使用位于英国的Co-operative农场的油菜籽来生产燃料,为建筑物的热电联合发电站供能。剩下的庄稼外壳会回收为动物饲料。多余的能量可以供应给电网,以及用在其他的NOMA开发项目(由Co-operative集团发起的英国最大的地区改造项目)中,废弃的能源会通过一台吸收式制冷机,用来给建筑制冷。

设计师也考虑到了全球变暖问题,从未来发展的角度根据2050年的预测天气数据采取了相应的措施。因此,即使未来夏季平均气温升高3到5度,冬季降水增加30%,建筑物也是可以应付有余的。建筑物的织物系统和环境系统经过设计,随着年平均气温的逐年上升会变得越来越高效。

其他的创新领域有:建立电池汽车的充电站,能源来自低碳的热电联产系统;开发了一种建筑用户“应用程序”,就建筑运行的详情提供实时的用户信息。

1 Angel Square contains 328,000 sq ft of high quality office space, specifically designed for maximum flexibilty. The building structure and its mechanical & electrical systems allow occupiers to easily reorganise accommodation and subdivide space, so as needs change, the building stays relevant – without excessive refit costs.It is the highest scoring BREEAM 'Outstanding' building the country, and sets a new national benchmark in sustainable design within the commercial sector.

1 Angel Square has been designed to deliver a 50% reduction in energy consumption compared to The Co-operative’s current Manchester complex and an 80% reduction in carbon. This will lead to a reduction in operating costs of up to 30%.

Ground breaking engineering features include a double-skinned façade to minimise heating and cooling throughout the year and underground concrete earth tubes that provide an amount of free heating and cooling for the incoming fresh air. The thermal mass of concrete is employed again within the building by exposing 300,000sq ft of concrete that forms the ceilings to the office floors.  The concrete acts as a thermal sponge, passively soaking up heat and reducing the amount of energy needed to cool the building.  Waste air is finally extracted over the balcony edge using the natural stack effect of the atrium thus negating the need for large space-hungry extract risers within the cores.   Before being expelled at the highest point of the roof, the air passes through a heat-exchanger that recyles the heat to warm the incoming air in to the offices below.

3DReid incorporated a recycling system for used water and a rainwater harvesting system to guarantee low water consumption.The Co-operative’s local sourcing and sustainability principles are put into practice in using rape seed from British Co-operative farms to produce the fuel for the building’s CHP power plant.  The remaining husks of the crop will be recycled into animal feed. Excess energy can be supplied back to the grid and utilised by the wider NOMA development, with waste energy being sent through an absorption chiller, used to cool the building.

The designers have addressed the issue of global warming and future-proofed the building against predicted weather data for 2050. So the building can cope with a potential 3-5 degree increase in summer temperature and 30% more rainfall in winter.  The building’s fabric and environmental systems have been designed to become more efficient as average annual temperatures rise.

Other areas of innovation are the implementation of electrical pool car charging points, fed from the low carbon CHP and the development of a building user ‘App’ which relays real time user information on how the building is performing.
